friction force: 12*.4= 4.8N
gravity force: 5N
gravity wins.
A 12 N horizontal force
pushes a block weighing 5.0 N
against a vertical wall (Fig. 6-26).The
coefficient of static friction between
the wall and the block is 0.60, and
the coefficient of kinetic friction is
0.40. Assume that the block is not
moving initially. (a) Will the block move? (b) In unit-vector notation,
what is the force on the block from the wall?
